congrats on your cart.......now if you plan on doing any upgrades this is the perfect time, as it is if you put it back to just a stock cart it has the most outdated speed system there is.......tell me it has a motor and a charger? anyways that being said before you dump any money in it ask your self what you want out of it.......stock you,ll go 12 to 14 mph and lose 1/2 of that going up inclines or hills and its the least energy effienct...........but since you need everything anyways i would really think about going to 48 volts...........save your money its an addiction with no cure other then coming here and seeing your not alone....................................

Thanks mkernan
I think you are correct. It appears that whoever had the car before I got it had hooked the batteries up wrong and caused insulation on two of the wires to burn. I plan to get 6 6V batteries and hook them up once I replace the bad wires. Do you know where I can find wiring diagram? Hopefully nothing else was burned.
Thanks
